rownnornnnrnn CLEANING BRUSH.

Application filed January 16, 1926. Serial No. 81,720.

This invention relates broadly to new and useful improvements inpower-operated brushes and has more specific reference to aWater-operated rotary brush.

An important object of the present 1nvention is the provision of arotarybrush adapted to be associated with a Water motor of any ordinary orpreferred construction, so that the Water used to operate the motor willalso be utilized by the brus Another object of the present invention isthe provision of new and novel means" for connectingthe brush with themotor, in such a manner that as the Water exhausts from the motor, itWill pass through thebrush and onto the object being cleaned.

Another obj ectof the invention istoprovide' simplified means "fortransmitting the rotary, movement from the driving shaft of the motor tothe brush.

, Another object is to provide such a brush having associated therewithmeans for carrying a quantity of soap or the like which 1s adapted to beused during the cleaning poration.

A further object of the invention is the provision ofnew and novel meansfor mounting the soap carrying means Withm the brush proper so that theexhaust Water fromthe motor will come in contact with the soap as itpassesthrough the brushonto the object being Washed,

A still further object is to provide a r0- tary brush of the characterstated Which will save both time and labor in'the cleaning of variousobjects such as the under surfaces of automobile fenders.

A still further object is-to provide such a rotary brush which Whilesimple in its con struction, is nevertheless strong, sturdy and durable,practical and efficient in its operation and an advance in the art.

lVith these and numerous other objects in view, the invention resides-inthe novelconstruction, combination and arrangement of partsto hemorefully hereinafter described, illustrated in the accompanying drawingsand more particularly pointed out in the appended claims. s a

In the drawings forming a part of this application and wherein similarcharacters of reference denote corresponding parts throughout theseveral views: 7

Figure lis a front view of a power-operated brush constructed inaccordance with the present invention,

Figure :2 is a side elevation thereof,

Figure 3 is a sectional view substantially on line 3-3 of Figure 1,

Figure 4 is a transverse sectional view on line l-4 of Figure 3,

Figure 5"is a detail view of a slight modification of the presentinvention showing an additional Way in which a hose may be securedtoythe Water inlet port,

Figure 6 is a sectional View on line 6-6'of Figure 5.

Referringmore particularly to the accompanying drawings and moreespecially to Figures 1 to 4; inclusive, wherein for the purpose ofillustration has been disclosed a preferred embodiment of the presentinvention, the letter A denotesas a Whole, a Water motor which may be ofany ordinary or preferred construction and in connection With which theimproved rotary brush B is adapted to be associatec lVhile, as statedabove, the motor A may be, of any ordinary or preferred construction,the type disclosed herein comprises a' sub stantially circular housing10 from one point of which extendsthe Water inletport 11' to which isadapted to be secured one end of a suitable Water conductor such as ahose or the like,t-h'e other end of Which may be secured to a suitablesource of supply.

Formed onthe periphery of the housing and extending in an oppositedirection to the-Water inlet port 11, is the water outlet port 12 havingsecured thereto one end of the tubular-jcoupling- 13 provided at itsopposite end With the bearing sleeve 14 arranged in substantiallyparallel relation to the Water outletport 12.

Mountedtransversely Within the housing 10 is the usual drive shaft 15projecting beyond the housing at one side thereof and having fixe'dthereto the Worm gear 16 adapted to remain in constant mesh with thegear 17 positioned at right angles thereto and fixed on the adjacent endof the shaft 18, the

outer end portion of said shaft passing through th'esaid bearing sleeve14. It will, i

of course, be understood thatthere is mount edon the shaft 15 Within thehousing'lO, a plurality of vanes, propeller blades" or the like so thatthe Waterengaging-therewith will arise the rotation of thesaid shaftWhich will be imparted through the gears 16 and 17 to the shaft 18. Itis not thought necessary, however, to disclose the construction withinthe housing inasmuch as it may be of any ordinary or preferred type.

Upon reference to Figure 3, it will be clearly seen that the upper endportion of the shaft 18 is formed with the longitudinally disposedelongated recess 19 and that also formed in the periphery of the shaftand con'inninicating with the recess are a plurality of openings 20,positioned directly opposite the opening in the tubular coupling 13 andadapted for selective registration therewith as the shaft is rotated,whereby to effect communication between the motor and the brush.

The brush B comprises in its construction a plurality of spaced invertedsubstantially U-shaped wire ribs 21 carrying the bristles 22 securedthereto in any desired manner such as by twisting the wires constitutingthe ribs around the bristles as disclosed in the drawings. The free endsof the ribs are suitably secured to the annular band 23 which in turn isbolted, as at 24, to the annular flange 25 formed on the periphery ofthe shaft 18 adjacent its outer end, said flange adapted to abut theenlarged end portion 26 oi? the bearing sleeve 14.

Arranged to be supported within the brush B is an elongated soapcontainer or cage C extending longitudinally thereof, said containerbeing preferably constructed of wire and comprising the foursubstantially parallel corner wires 27 and the intermediate longitudinalside wires 28, these wires being connected by the inter-woventransversefivires 29. Carried by each of the corner wires adjacent itsopposite ends are the wire hooks or clips 30, the free ends of whichengage the ribs of the brush as indicated at 31 whereby to securelyretain the container in its proper position within the brush.

This container is adapted to carry a quantity of soap or the like andsecured to the end thereof adjacent the motor is a conicalshapeddeflector 32 provided to spread the water as it enters the brush.

In the operation of the invention, it will readily be seen that as thewater enters the housing and through suitable means contained thereincauses the rotation of the shaft 15, this rotary movement will betransmitted to the shaft 18 through the worm gears 16 and 17 andinasmuch as the brush is secured to the flange of the shaft, the samewill also be caused to, rotate. As the exhaust water passes out of thehousing through the outlet port, it will be conducted through thetubular coupling 13, and thence into the brush through the spacedopenings 20 and the recess 19 in the said shaft 18. The water engagingwith the deflector 32 will be spread in all directions and as the brushcontinues to rotate, this water will run over and come into contact withthe soap or the like within the wire cage C before it passes through thewire ribs of the brush onto the object being cleaned. In this manner,the water as it comes into contact with the object being cleaned willhave mixed therewith a quantity of soap whereby to cii'ect the easycleaning of the object.

In Figures 5 and 6 has been shown another way in which a hose may besecured to the water inlet port of the motor and by reference to thesefigures, it will be noted that there is provided the motor A comprisinga circular housing 10, provided with the water inlet port 11. However,in this term, there is secured to the water inlet port 11, in anysuitable manner, such as by means 01? the bolt 3:2, a bracket 33 to theouterend of which is secured the bight portion 31 of the clamp 35 havingthe arcuately curved resilient arms 36 and 37, the free ends of whichare provided with the lugs 38 and 39 through which pass the bolt 40having threaded upon one end thereof a wing nut or the like -l-l, theportion of the bolt intermediate the said lugs 38 and 39 being encircledby the coil spring 42 which acts to norn'ially urge the spring arms 36and 37 apart.

The numeral 13 denotes one end of a suitable hose, the other end ofwhich may be attached to the source of water supply in any desiredmanner. In the application of the clamp, the wing nut 11 is firstloosened so that the spring arms will be forced apart by the action ofthe spring 42 to a degree suliicient to permit the insertion of the hosebetween the same and the water inlet port, it being of course understoodthat the hose is slipped over the said inlet port. The wing nut 11 isthen subsequently tightened whereupon the spring arms 36 and 37 of theclamp 235 will engage the hose i i and clamp the same tightly onto theutter inlet port 11.

From the above. it will be readily appreciated that there has beenprovided a new and novel \\'atei.'operated rotary brush which willaccomplish all of the objects and perform all of the functions claimedhereinabove. Also. that while there has been illustrated and described apreferred embodiment thereof, it is to be understood, that variouschanges or IllOCllliCfltlODS in the details of construction may beresorted to without dcparting from or sacrificing the spirit of theinvention so long as these modifications or changes fall within thescope of the appended claims.

lVhat is claimed is:

1. A brush head structure designed to have water forced into theinterior thereof. comprising a base plate, having a passage therethroughfor the extension therethrough ill) of a discharge end of a water pipeand a plurality of inverted substantially U-shapedsaid element, aplurality of inverted substantially U-shaped frames extending outwardlyfrom one face of said plate and having the free ends of their legssecured at diametrically opposite points in the plate, bristle memberssecured to and projecting outwardly from each of said frames, and aforaminous soap receptacle adapted to be mounted Within said head, saidreceptacle having an imperforate bottom of 001110211 shape designed tobe arranged over said Water CllS- charge element to cause water tobespread laterally Within the head.

3. In combination, a brush head structure adapted to be revolublymounted upon a Water discharge element, comprising a base plate bodydesigned to be secured to said element, a plurality of invertedsubstantially U-shaped frames, extending outwardly from the face of saidplate and having the free ends of their legs secured at diametricallyopposite points in the plate, bristle members secured to and projectingoutwardly from each of said frames, a Wire soap cage structure arrangedWithin said head, and a plurality of clip members extending from the allof said cage to and engaging said frame legs to suspend said cage inposition Within the head.

In testimony whereof I aifix my signature.
